So last season, I noticed my female 'spotting' her enclosure with little dabs of urate, especially when I put the male in with her (she also did lots of tail wagging when he was near which was interesting to see). I put the dabbing down to either a) scenting, or b) nervousness.
Yes they do scent their enclosure when a male is in with them. Its them basically saying "come get me" I've never seen my females scent without a male in their tubs
